I know it’s a regular occurrence and just wandered what other people did. I was on the A9 today sat at 50 average speed cameras. Anyway I had white van man overtake me with another one coming towards me. The guy overtaking doesn’t realise he isn’t going to make it until he is half way along my trailer. The question is what would you do? I chose to maintain my speed and let th sort it out and just be ready for one of them to come into side of me. My theory being if I accelerate anticipating he is going to brake so he can fall in behind me he might just decide to accelerate to try and clear me so making the problem worse and if I brake to let him get past quicker he may brake realising he isn’t going to make it and again I make the situation worse. As it happens both vans braked and he managed to get behind me but it was the closest one I have seen without an impact. He past me sheepishly one mile later at the dual carriageway.
Seek out Roger Franklin to get your answer then do the oppisite of what he tells you and you should be ok 
Always avoid an accident if you can, saves so much aggro and you don’t get ripped on here. Be the better person and don’t let it bother you.
Think I would have eased off & got as far left as possible , then let him carry on with his little game.
I agree with Mailman, try to avoid, don’t be like the Numpty on the M6/M5 junction & block the caravan, knowing that they were going to collide.
2 wrongs don’t make a right !
I often wondered about this like you said if you slam the brakes on what’s to stop him doing the same and unable to pull in behind you! When ever it was me I take my foot off and hope the person will accelerate off quicker and get in front or slam there brakes on so will be slowing down a lot quicker than me so can pull in behind! I’m sure what ever happened we would be the people getting the blame somehow!
Brake and over to the left. No truck is going to outbrake a van
There s no right and wrong answer because each situation will be different
You will probably have a split second to decide what to do for a particular situation
When I see someone pull out to overtake me on a single carriageway, I tend to ease up a little to help them pass. Try and avoid a situation before it becomes one.
Always tricky these ones as it can be a damned if you do damned if you dont situation, I usually do all I can to ensure both vehicles collide, in this case sudden braking and acceleration may have got the job done.
Usually best to start accelerating as soon as they commence the overtake then they feel a race is on the cards and pay less attention to whats coming at them, if theres another motor approaching in the opposite direction then happy days and brace for a wallet pinching opportunity as one of the vehicle occupants will be trapped and perhaps even a groping opportunity with injured females (or males, whatever floats your boat).
I am of course joking and each one can be a judgement call and preserving life takes priority, whatever you choose to do stick to it and be decisive unless unfolding events require more drastic action. Split second decisions are part and parcel of this game, some we get right others can go drastically wrong.
If you brake and there is still a collision, you can’t be held responsible.
If you don’t brake and there is a collision ----------------------?

correct answer I’m sure it’s in the Highway Code. 
BUT AS SUPERIOR CLASS ONE ARTIC DRIVERS NO ONE SHALL PASS!

Thats exactly what I was going to say.
If you brake,and he brakes,and a collision occurs you tell plod you saw he wasnt going to make it and braked it will be taken as you trying to avoid the collision and van ■■■■ will get the blame.
If you keep going,or even accelerate,and a collision occurs and you tell plod you wanted to let it sort itself out then youll end up with some of the blame.

You are of course only joking if no dash cam is present? I mean,if you have a dash cam then you have evidence you are 100% innocent and can provoke a collision to boost your youtube profile,get your FB mates to “like” your footage and then the holy grail,post it on here for al to see how utterly pro you are and how many idiots on the road there are?
In the car at night, Mr Audi itching to overtake on a NSL country road, I will start to pull in and slow down a bit and let him pass. Even get thanked for it by 4 blinkers. No skin off my nose - got the road to myself, no headlights behind.
Also, if someone wants to pass riskily, you have the think about any oncoming cars who are innocent in the whole scenario.
As has been said this is a difficult one. Two things seem to stick out like sore thumbs, your responsibility towards the vehicles coming the other way, and perhaps the reminder that a more frequent check on the mirrors just might prevent the situation developing in the first place.
On single carriageway at night, if I can see a car behind me then I’ll look ahead, if it looks clear I’ll flick my left indicator on 2 or 3 times and move over to the left as much as k can without ending up on the grass, every time so far the cars come out, zipped passed and given me a flash of the hazards.
On the flip side, if there’s someone behind me itching to get past and it isn’t safe, I’ll keep right as much As possible every time they poke their nose out, seems to work most of the time although a token Audi driver overtook me on a blind uphill bend the other night, thankfully nothing came round the corner.
The best thing to do in this situation in my opinion is to let the accelerator off and pull over to the left as far as you can. The reason you shouldn’t brake is because you and him are going to realise he won’t get past at the exact same time so the two of you end up braking at the same time leaving him nowhere to go only head on into the oncoming car. So my advice is just let off the power, keep in and let him and the oncoming car do the braking.

I do this as well, day or night, but so many of them still dither (maybe remembering not the nine o’clock news 
). Did it to a copper the other week heading into goldtjorpe - he was waiting for me when I got to the next roundabout - I was expecting a bollocking for something or other, but instead got a ‘thank you, good to see somebody who thinks’!

Got the same one night, done my indicator trick and the next day got a thank you from our tour manager who I’d unknowingly let pass me. Nice to know that the coppers don’t frown upon it as well.
I’d much rather get someone past me and get them out of the way than have them sat right up my backside. Seems safer to me.
Always find it’s easier to let people past as saves a lot less hassle for all concerned plus if you keep them behind you they may be the type to pull in and test your brakes , not good in a loaded artic
